Stacks Labs Completes Post-Quantum sBTC Transaction on Mainnet
Stacks Labs says a test-vault withdrawal moved sBTC on the Stacks mainnet using a post-quantum signature scheme.
Stacks Labs says a test-vault withdrawal moved sBTC on the Stacks mainnet using a post-quantum signature scheme. Stacks (STX) is trading at ₹29.13 ($0.31), down 1.3% since this brief published. This is an original Token Times brief based on reporting by Crypto Economy, with live market data added, as of Wed, 11 Nov 2026 23:00:01 UTC.
The transaction provides a mainnet demonstration of post-quantum signing within a Clarity smart-contract workflow, moving the approach beyond theoretical or test-only validation. It also highlights how blockchain infrastructure may test alternatives to conventional cryptographic signatures.
- sBTC moved from a test vault using a post-quantum signature
- The transaction ran directly on the Stacks mainnet
- Validation used a hash-based Lamport one-time signature scheme
- STX trades at $0.314268, down 11.00% over seven days
Stacks Labs reported completing what it described as the first sBTC transfer protected by post-quantum cryptography directly on the Stacks mainnet. The operation involved withdrawing funds from a test vault implemented through Clarity smart contracts, placing the test within live blockchain infrastructure rather than an isolated environment.
The transaction was validated with a hash-based Lamport one-time signature scheme. Crypto Economy’s report said the transfer tested how sBTC could move using post-quantum signing, although the summary did not provide the transaction amount, timing, or technical performance results. The withdrawal source was specifically a test vault, not a described transfer of general user funds.
Only Crypto Economy covered the development, and Stacks Labs supplied the reported result, so the “first” designation has not been independently corroborated in the supplied material. No additional outlet reported a different transaction size, method, or implementation detail, but the single-source status means broader verification is limited to the available report.
STX was priced at $0.314268, up 0.44% over 24 hours but down 11.00% over seven days. Its market capitalization stood at $591.26 million. The wider crypto market was flat with a total capitalization of $2.54 trillion, while 
Bitcoin gained 0.85% over 24 hours; the Fear & Greed index registered 29, indicating a Fear reading.
The development matters primarily as a practical demonstration of post-quantum signature validation in a Clarity-based sBTC workflow. The available report does not specify deployment plans or indicate whether the method will be adopted more broadly, leaving the scope of any wider rollout and the transaction’s technical results as points to watch.
Since this brief published about 1 hour ago, Stacks (STX) has moved from ₹29.53$0.3143 to ₹29.13$0.31 — -1.35%.
The chart plots STX's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from Token Times's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 STX ≈ ₹30.81 (about $0.31), down 0.8% over 24 hours. The rupee itself trades about 5.8% above the official rate on the P2P market, so a Indian buyer's effective cost differs from the headline dollar price.
